ok first thats not a bad list id just switch pcp and E. Now i have a good reason for this. Now extremely limited use of E is minorly damaging because it burns a small hole in the part of your brain that controls emotions, now this releases a natural chemical that puts you in an extremely euphoric state and your emotions are magnified. Now if you do this to often however your body will never produce this chemical again and you will for the rest of your life be in a severe case of depression that can not be cured with anything, anti-depressants even more E will do nothing, so if youre gonna do it, do it extremely rarely. Now coke #6 is also a damaging drug because its addicting as shit and it makes little bugs crawl under your skin(yes this is true) and if you drive while high on coke youre gonna be going extremely fast and trying rediculous shit you would normally never do, #7 can be bad to if you do it alot because you can be addicted and if fucks up your liver, now if you only party on weekends and drink beer only its effects are much much less severe, #8 LSD this is actually damaging even if you arent having a bad trip and freak out, now some people believe that it never stays in your system but infact it stays forever in your spinal cord, now alot of this also can be damaging you can become paralyzed from this (it takes a lot though). and of course #9 Pot, yes my personal favorite, now the actual drug itself isnt really that damaging, now smoking it obviously the smoke hurts your lungs any smoke hurts your lungs, but if you dont want that make brownies and youre all fine no cancer, oh and at times it can cause temporary paranoia(at worst) but is used around the world for diseased patients to induce hunger. Oh and ive seen pot actually do damaging shit, people i know started out with pot then moved on to coke for some reason because they wanted more than the feeling of pot so if youre like me and do weed, dont do anything else
