Recreational substances and retatrutide

Summary

How do GLP-1 drugs like retatrutide change the effects of recreational substances such as cocaine, LSD, MDMA, ketamine and mushrooms?

Users report markedly weaker responses to cocaine, LSD and MDMA while on retatrutide, with little or no dopamine rush or typical euphoria. Ketamine and 2C-B appear less altered, while mushroom effects vary by timing relative to the injection. Several participants note the same pattern with prescription stimulants and discuss the value of sharing these observations for harm reduction even if forum rules later restrict the topic.

Just returned from Shambhala Music Festival, my annual spot for letting loose. Since many combinations remain untested I thought sharing what happened could be useful. Cocaine barely registered at all with no dopamine lift. I can see why these GLP-1 drugs help some people drop that habit. Acid on the first night felt like my friend had weak or old stuff because nothing occurred. Even switching to another source that had worked great for someone else the previous evening produced zero results. MDMA arrived in a mixed capsule probably containing MDA or speed. The blend is meant to turn pure MDMA into more of a dance drug instead of a pure hug-and-love experience. The effect felt much gentler than usual with none of the nonstop talking or total contentment. It was pleasant but far milder. 2CB was new to me so I had nothing to compare against. It stayed mellow yet enjoyable with light visuals and a modest energy lift. Ketamine showed almost no difference.

Bringing up schedule I substances looks like a fast route to getting the thread removed.

Curious how this might change things for people who rely on prescription pain meds for ongoing pain. Anyone seen any personal reports?

Strange. I posted about ketamine earlier. I will check the rules again because I do not want to get removed, I only want to pass along what I noticed.

ClearLantern70archiveJul 30

Thanks for putting this up. I stay away from those substances but the details are still helpful. I do drink and I am trying to stop.

After reading the rules there is still no direct prohibition. The owner might add one later and I would accept that. Harm reduction is mentioned and talking about drug interactions fits that goal. Someone might think their cocaine or MDMA is weak and take two or three times as much without realizing the reduced response is expected. That could lead to lasting harm. Putting the information out there can actually reduce risk.

Ketamine is schedule III. Anyone can read the forums. We probably do not want the site linked to schedule I use. It does not look good. I expect this thread will be deleted.

The schedule itself does not seem central to me and I am not even in the US. I hope people focus on the harm-reduction angle the rules mention rather than an old war-on-drugs view that has not helped the country or this forum much.

KeenKettle50archiveJul 30

Either direction looks risky. The safest move is to skip the topic.

What are you getting at with that remark?

QuietMarble33archiveJul 30

This is interesting. Maybe replace certain words with emojis to stay safe?

I looked at the rules again this morning. Which words do you think would get a post removed and why? I am asking seriously.

GreenMeadow54archiveJul 30

The ban threat was mostly a joke. No one meant any harm so I doubt you would actually be removed. Still, I expect the thread will disappear. Peptides already draw enough negative coverage without adding schedule I talk.

LevelAlder29archiveJul 30

My festival days are behind me but the details are still useful. Ketamine sees plenty of medical and psychiatric use so from a clinical view this helps medical staff. Thanks for testing and posting. Even if the thread gets taken down I will add that a well-educated friend who runs spiritual retreats with a traditional Peruvian substance starting with Ay. says GLP-1s are not ruled out but the shot should be timed well away from the event, roughly six or seven days. She did not address how the substance itself might change for GLP-1 users. Tirzepatide does not seem to alter cannabis when smoked, vaped or drunk, but edibles hit much later because digestion slows down. The effect still arrives, just out of sync with everyone else.

The schedule I label is an artificial idea everyone recognizes as flawed. MDMA and LSD have been studied for medical use in many places including the US. They carry less addiction risk than legal substances like tobacco or alcohol. Even recent FDA peptide hearings showed how unserious the arguments were. Keeping these compounds banned only pushes people toward riskier options. Removing discussion of how peptides interact with other substances also removes information that could prevent harm. The idea that users will simply avoid all other compounds is unrealistic.

I agree the information is worth sharing. Many people use recreational substances and most doctors or studies do not cover how they interact with prescriptions. Even if reactions differ between individuals, this serves as a reminder that GLP-1s can change how those substances behave.

Mushrooms work normally unless taken the same day as the retatrutide shot.

ClearKettle55archiveJul 30
↳ replying to @SteadyAnchor73

That is useful to know. I skipped mushrooms after the acid produced nothing.

SlowLantern99archiveJul 30

Since it would be unrealistic to act as if these topics never come up and laws differ worldwide, the thread can stay for now. I have made some edits and expect everyone to act responsibly.

AmberLantern34archiveJul 30

Thanks for testing and reporting. This makes me reconsider scheduling events involving mind-altering substances while on reta. I already suspected dopamine-related compounds would be affected. I have a couple of events coming up and will try to keep the GLP-1 dose as far away as possible. Losing weight has let me dance longer while staying completely sober, which I enjoy.

To be honest I enjoyed the festival more with the reduced effects than any of the previous ten times. I felt clearer and had better conversations. I was disappointed at first but would not change anything now. I could spot friends in huge crowds, remember brief meetings from days earlier, and connect more genuinely. The goal of the post is to set expectations and strongly advise against doubling or tripling doses. Just because the usual positives are missing does not mean the negatives disappear. I would not trade the clearer head I have now for stronger effects. Hope your events go well and please share what happens so others can decide with better information.

GreenMeadow27archiveJul 30

My usual mushroom amount stopped working once I started tirzepatide. I have to take quite a bit more to reach the same level.

BrightHarbour13archiveJul 30

I do not support using any of those substances and it seems counterproductive while optimizing health with peptides, yet these reports remain interesting. The retatrutide anecdotes keep surprising me.

SteadyLedger49archiveJul 30

Steer clear of tesofensine with any of those substances because it dulls the experience even more.

I was surprised to learn my local dentist now uses ketamine in procedures. It would be worth asking their office whether they notice any differences with patients on GLP-1 drugs.

CopperSignal27archiveJul 31

I take prescribed dexamfetamine. Before ozempic two years ago I could clearly feel when a dose kicked in. Once I started ozempic that sensation vanished. The drug may still have worked somewhat but the effect felt reduced and I lost the ability to tell when it was active. Slowed absorption might play a role but changes in dopamine signaling seem more likely. It is frustrating because the medication was more useful before.

ClearKettle55archiveJul 31

That fits the pattern in this thread. It is helpful to see how many different compounds get dulled by these GLP-1 drugs.

Many of these substances are used for mental health and therapy work, not only recreation. They are also legal in various places including parts of the US.

Glad you posted. Two of the substances matched experiences I have had and I have not tried the rest.

SlowSparrow78archiveJul 31

This is useful information. Whether or not someone uses them, these substances are more common than some realize. Sharing personal results helps others who do use them. My own days with them are long over because my mental health cannot handle the downsides anymore. If I had not felt the usual effects while on GLP-1s I would probably have taken more trying to recapture the old feeling. It also raises the question of whether reta could help people dealing with addiction to these substances. I switched back to tirzepatide recently but my prescribed ADHD medication did not seem affected by retatrutide.

That is a handy set of observations. I am heading on holiday in two days so now I know not to spend money on cocaine. Thanks, you saved me some cash.

NorthFenwick23archiveJul 31

Good idea to talk about these interactions. I have been wondering whether my migraine medication has become less effective lately and I am also on reta.
