LSD is a psychedelic drug first synthesized by scientist Albert Hofmann in 1938. It became increasingly popular as a recreational drug in the 1960s.
Capsules – swallowed, blotter – left on tongue to dissolve
The following information on dosage was taken from PsychonautWiki, but this should not be taken as a recommendation: duration and effects of any drug will depend on purity, regularity of use, other medications or drugs you have taken, your body and how it is taken (route of administration).
Swallow:
An average dose for sublingual (under the tongue) administration is around 75μg (this dose should not be taken as a recommendation). A slight difference in dose can create a different experience or effect.
A tab of LSD can contain anywhere from 0 to 300+ µg (micrograms) of LSD. Often, tabs fall between 100µg and 200µg. When buying, there may be suggestions of what strength the tab of acid is but there is no reliable way to confirm this other than starting at a low dose and seeing what effect it has. So, try starting with a quarter tab (tabs should be cut diagonally across the paper) leaving at least 3 – 5 hours for the strength of effects to peak. Remember, you can take more but you can’t take less.
LSD is a lab-made drug, so the potency and strength can differ. As a result, the strength of a tab can vary significantly, especially if the LSD was absorbed unevenly in the production process.
General information on dosing.It can take up to an hour to feel the effects which can last from 6-12 hours.
LSD can alter your senses and thinking, causing colours to appear more vivid and music to sound clearer. It also increases your heart rate and blood pressure. People using it can experience a high, spiritual insight, wakefulness and reduced appetite as well as a feeling of time slowing down, confusion, anxiety and paranoia.
Negative effects will pass – telling someone that you are experiencing them or changing environment can help reduce these feelings. The experience you have will depend on your mind set and the environment also known as set and setting.
