Do people abuse hallucinogens for the euphoric and happy feeling they experience?

Question: I think the use of hallucinogens tend to be illegal because people abuse them to the point where it become hazardous. Some people argue that legalization would result in an decrease of crimes. While others argue that it’ll increase the crime rate. Most believe that since people already do it they should legalize it. Some arguments about other classes of drugs such as depressants, stimulants, etc. are that people wish to get off of them. For example Methamphetamine is a stimulant that speeds up the body’s system. I’ve never spoken to someone that has done or was addicted to meth, but I have watched videos. The videos that I’ve seen on why they did it and how they became addicted to the drug usually is because of life issues, or someone introduced them to it. People abuse drugs thinking that the drugs is their only escape. People aren’t satisfied with the hallucinogenic properties being removed because they like the feeling of hallucinating. For example most people who smoke marijuana usually refer to their feeling as being “on cloud 9”. Which means euphoric or happy. What is your response to this?
