hi, im from Iran. and i tried crack cocaine about 2 months ago, i researched a bit, and find out. the price is ridiculous. it's about 1,700,000 (40$) Rials in border and you can find it in the cities for about 2,500,000 (60$) Rials. i searched a lot of online markets and this price is to low. im pretty sure the crack here is not pure. but i have some question. is it possible to make cocaine at home? or there is some drug like crack? in the rock form for inhale. is it possible to buy pure crack for only 40$? how can i test the purity? is there any alternative to crack beside meth?
