These drugs disrupt interactions in your brain, resulting in hallucinations and changes in the perception of all five senses. They can also completely change the personality of the user.

Probably the most common hallucinogen is LSD (also known as acid).

The side-effects of hallucinogens can include:

• sudden changes in personality
• fear
• paranoia
• psychosis
• distorted thinking
• nausea
• elevated blood pressure

Did you know that the side effects of hallucinogens can be permanent and life-altering- including the potential for permanent flashbacks- which are occurrences of visual symptoms similar to the ones experienced when on the drug?
