Traditionally, a "heroic dose" is 5 grams at a minimum. Well, that's the conventional wisdom, anyway.

But Psilocybe cubensis shrooms vary widely in potency due to genetics and growing conditions, and reactions between individuals to a given dose size also vary widely. Tolerance accrued from recent dosing is another variable, not to mention that set and setting can cause one individual to have widely different experiences on the exact same dosage.

In short, even if you gave some information about the intensity of the two trips you've had recently, there is no sure way to answer your question. If it were me, I'd space future trips at least two weeks apart, and increase the dose 1 gram each time using whatever supply of shrooms you already have in stock. This is assuming all your shrooms were harvested from the same grow, and then ideally you're also able to work with shrooms from the same flush as the shrooms you've already dosed. Potency can vary quite markedly from one flush to the next.

I always phase in shrooms from a different flush, so when my first-flush shroom supply is running low, I start taking doses that are a mix of first and second flush shrooms. That way if the second flush is much more potent than the first I don't get floored with a wildly stronger experience than I bargained for.

Yeah, I try to avoid dosing with a tolerance. In my experience the trips lose much of their magic, closed-eye visuals no longer happen, and things get rough and anxious. There might still be a few sweet spots, but overall I get the feeling my brain has been fried.

Others doubtless have a different take on this. Currently I'm dosing once every three weeks, and after continuing this pattern for half a dozen trips things are going all right so far.

I feel much more hopeful and my faith is in the right place, really I just wanna kick cigarettes.

Maybe a few low doses will do it

If it's any consolation, I actually tend to find smaller doses are more helpful for me if I have a really specific intention like that.

Bigger doses seem to not give a fuck about my intention and just have their way with me Still very helpful in their own way but more of a factory reset than anything else in my experience.

But of course everyone is different

Magic mushrooms could help people quit smoking

Nicotine is highly addictive, but new research is showing that psychedelics can shift people's worldview in ways to help them give up cigarettes.

Tobacco is one of the toughest drugs to quit. The nicotine it contains is as addictive as cocaine and heroin – perhaps even more so. In surveys, around 70% of adult smokers say they want to quit. Yet of those who try, less than one in ten succeed in any given year.

Evidence is growing, however, that certain psychedelic drugs might offer some people an off-ramp from smoking. In a 2017 survey, for example, 781 people said that tripping on LSD, magic mushrooms or another psychedelic had either allowed them to reduce smoking or quit altogether.

Why? The solution seems to be of the philosophical kind. Nearly all of those who managed to kick their nicotine habit reported a common insight: they suddenly felt that their life priorities or values had changed – specifically, that smoking no longer served them.

"The magnitude of the experience kind of overshadowed this previously insurmountable psychological challenge of quitting smoking," says Matthew Johnson, lead author of the study and a professor of psychiatry and behavioural science at Johns Hopkins University, in the US.

And it is not just anecdotal. These findings have held up in a laboratory setting, too. In March 2026, Johnson and his colleagues published the most robust evidence to date showing that talk therapy combined with one dose of psilocybin, the primary psychoactive compound in magic mushrooms, is significantly more effective for helping people quit than therapy combined with nicotine patches.       

Six months after undergoing treatment, the 42 people who had taken the dose of psilocybin had six times higher odds of having quit smoking than those in the nicotine patch group.

'If in doubt, double your dose.'

That was the way to go for me for several years. Though, these days I find lighter trips more rewarding.

But if you feel the call for a massive dose... just do it, follow your intention. Guys from an internet forum can't really help you as all answers come from individual personal experiences. Your situation is unique and only you can tell or sense what is best for you.

A week is usually enough to reset most of any tolerance with tryptamines.

It's not just the intention to quit cigarettes it's also about the intention to stop overthinking, let go of the past, move on from people who will never accept me and be content without a social life. Yeah. I need a big dose.

I know all about waiting 2 weeks, I usually wait 4 weeks or longer, I have personal reasons for wanting to go again 6 days after last dose

Where did you get 2 weeks from? 1 week is enough to reset tolerance.

As a public service announcement/harm reduction, a great way to wind up in the emergency room is to jack up a drug dose a lot higher based on perceived - but in reality, non-existent - tolerance.
