Nah man, I know a guy in prison for having weed. You'll stay in jail until the judge gives a nod, and guess what, the judges here are focking lazy. He's been 5 months in prison waiting his trail.
It Depends on high (not drug high, socially high position) you are here, man. If let's say your uncle/family member is working with the 7okomeh/mo5abarat/majles nowab you get away with it easily. If you're a peasant/nobody like me it's the end of your life.
The problem is not with you getting caught, it's with the dealer getting caught. It's hard to get caught if you smoke in your home, and we don't have the advanced testing devices here so you're safe if you smoked weed. They only test blood (which THC remains maximum of week in) and urine which up to 2 weeks, they don't test hair follicles which the THC remains for 90 days in.
But the problem is, when your dealer get's caught, you're fucked too. Dealers get beaten up and tortured until they hand the police the name, location and number of every customer.
