How? How Much? When? For how Long?

As with any drug, the correct dose for you depends on factors such as weight, gender, metabolism, whether you have taken the drug recently or not, amongst many others.

Read our Me sections on dosing and tolerance for more information.

How you take it matters...

LSD is always taken orally and it is only injected for research purposes. It is commonly dissolved in blotting paper that can be broken down into tabs. other, less common, ways of taking this psychedelic are consuming it in the form of liquid LSD and gelatin

You should place the tab under your tongue for around 10 minutes, after that, you can safely swallow the tab.

If you are going to try LSD for your first time or you are using a new source, we encourage you to take a low dose to avoid a bad trip.

How much?

Low: 25–100 µg (people report feeling some effects with as little as 20 µg)

25–100 µg (people report feeling some effects with as little as 20 µg) Medium (common): 65–175 µg

65–175 µg High: 175–250 µg

175–250 µg Heavy: 250+ µg

When do the effects kick in?

The START time below is when you will usually begin to feel the effects of LSD from the time when you first take it. DURATION is roughly the length of time you will experience the effects, after which the effects will start to wind down and you might start to feel the calm-down/comedown effects.

Start: 30–90 min

Peak: 2–3 hours

Duration: 9–14 hours

This depends heavily on the person and her/his state. Factors such as heart rate and blood pressure or the presence of other drugs in the blood affect the time the drug will take to have an effect. A higher heart rate and blood pressure than normal would make the effects to kick in faster. This can also vary with how much you have taken: the higher the dose you take, the longer the trip will last.

How often can I take it?

Psychedelics are powerful substances and individuals can often find themselves overwhelmed by the new experiences they have gone through. After their first LSD experience, it is not uncommon for individuals to feel like they never need to take LSD or any other psychedelic again. Think carefully to see if this applies to you.



If you are intending on taking it again, for first time users, it is recommended that individuals wait at least three months before dosages in order to properly integrate what they have learned into their everyday life. For more experienced users, the three month resting time is also recommended. You may, however, feel like you can dose sooner than this. Even so, due to the powerful nature of the experience, it is advised you do not take LSD or other psychedelics more frequently than this.



Acid tolerance rapidly builds within the first few hours of consumption. After just two hours, re-dosing will have little to no effect on the experience. This tolerance will last for up to two weeks before it wears off completely. It is therefore advised to avoid re-dosing entirely.



Furthermore, there is a cross tolerance between LSD and Psilocybin (Magic Mushrooms). Taking LSD on Day 1 will mean taking Psilocybin on Day 2 will have little to no effect. The same also applies vice versa. Two weeks must be given for the cross-tolerance to completely fade.
