Who shouldn't take hallucinogenic drugs?

I know there are different categories of drugs such as dissociatives (ketamine, pcp, dxm), mood-altering (cocoaine, meth, ecstasy), and hallucinogenic (lsd, shrooms, mescaline). I am curious about hallucinogens. I know that they are not for everyone, like if you have a family history of mental disorder or if you are not in a good mood then you should not take them, but i want to know what kind of people should not take hallucinogens, or what personality traits might be a sign that these kinds of drugs are not appropriate, (ie: people who always need to be in control should not take them...ect), preferablly from people who have used hallucinogens.

if you feel the need to leave an answer such as "dont do drugs at all" or anything immature and cynical to my question then please don't waste your time. i can't help but feel sorry for people who have enough spare time to go from blog to blog just to post their opposing opinions and start fights. even if you did, i wouldn't respond.

People who have to ask whether or not they should be taking them should not take them, because obviously they're a bit worried that they shouldn't be taking them, and if they are worried they will have a bad trip.

if you don't want to hear an answer people might put out there don't ask a question....

Hallucinogenic drugs often have long lasting ill effects on a person's brain. These effects often build up and can cause permanent brain damage.

u seem a bit anxious about it (like i was) so you need to have a drink or two before throwing some schrooms back or whatever it is ur down for.

Just mix and it'll be ok.

just be in a happy mood when you use it to insure a pleasant trip....but if you are unhappy and depressed or at all consumed with a problem,, then this sure aint the time for it.
