Coke is not overrated but demonized like anything else efficient but either not easy controlled by pharmaceutical demons or too expensive even if they could get the control over its distribution, production etc. they would earn much less then what they do now and sell mainly the cheapest stuff to maximize income. Like this they have the solution for each pocket, and full control over the market.
Coke is ten, hundred times better antidepressant, and very well tolerated and safe in sane dosage. It is addictive because people are trained, brainwashed and hypnotized to fulfill their own expectations.
I am not alking about smoking base here or iv.
Regarding antidepressant effect, there are reports where only one dose per week would help people who didn't respond well to other common antiderpessants. I personally started feeling joy (normal, not 'high' like joy), after almost a decade, after I had started doing coke approx once per week, or once in 7-10 days. On coke I feel easily stimulated, get in a nice mood, a normal one, maybe bit exited sometimes, I also noticed that physical work, like doing workout, caring heavy things around etc. is noticeable more easy on coke, but I didn't noticed this before I started 'working'. Of course it has it's risks, but viagra has these too.
I personally do not feel psychically addicted at all. I have started increasing the periods between doing it, because I have noticed my mood has improved drastically.
One shouldn't forget people mix coke with alcohol very often so remember this when someone accuses coke for silly, stupid actions. Another culprit is ego and people with complexes. Such people 'know' coke will make a superman out of them, so they behave accordingly. This is my subjective experience, and I am human so I could be wrong. Besides that it is illegal and people say it is evil drug which makes zombies out of pure innocent souls, someone's son, another man's brother turned to criminal because of it etc. So kill it with fire. Criminal what a word, basically or often means you did something few corrupted politicians said is forbidden..
