...they get more tripped than less? I am doing a project..

Like lets say they took 20 or so hits would there be a point where they did not get more high or effected. Like if they took 2500 micrograms verses 25000 micrograms. Also if a person took a massive dose would they trip for days or would they trip harder but come down sooner?

Also have you ever seen anybody take a high dose and not recover that was sane in the first place?

Also look at this video of a cat. Is this what a high dose would do to a person. Would it disable there nervous system like this...
