research chemicals, especially the addictive ones like stimulants and noids, because this situation has truly become hellish. especially synthetic cannabinoids, which seem to have the remarkable ability to let people forget about minimum safety standards and just keep continuing their daily weed habit. gram after gram, substance after substance, blend after blend. mostly with the newest bleeding edge molecules these days, since the more known ones are banned in many countries now. playing the brave, occasional test pilot is one thing, being the 24/7 guinea pig another. no wonder every second noid-post here is because of some panic attacks. people have every rational right to be panicing and getting paranoid in a scenario like this. one could call it survival instincts. use them, it certainly did work for me.
heroin. because no matter how hard you try, it will drag you down on multiple levels, especially those levels youre not paying attention to. if its not the habit, its the job or the social interaction or changes in moral thinking, etc. and before you know it you get caught stealing/messing up at work, get fired and then you have a stronger tendency to develop your habit after all, stuff like that.
crack, because its like cigarettes, developed to be addictive as possible. no need to feed an industry.
cigarettes, for the exact same reasons as for crack and because theyre like health hazard nr 1 and i could get so much older without them, without missing anything at all. wasnt too hard to quit smoking actually with help of electronic cigarettes, they are so much better than the pyros. also nicotine has quite recreational value as a stimulant, if consumed isolated and with a nice flavor.
