L.S.D. is a class 'A' drug according the misuse of drugs act. L.S.D. is not physically addictive like tobacco for example, but it can become psychologically addictive - habit forming. It works on the five senses and can induce hallucinations of all the senses. One of the most important issues with using acid is that it is very much related to the environment, the person and the drug. The time, place, the mood your e in and the dose of the drug is never the same.
People experience dilterent trips every time.
If you are in familiar surroundings, feeling happy and relaxed, you are more likely to experience a good trip, than if you are in strange surroundings feeling sad or scared. Like all drugs, acid enhances the existing mood you are in. This drug can bring on mental health problems because of its strong effect on the mind. This will not happen to everyone as some people are prone to problems and some are not.
