Albania is not the place you wanna be fucking around with drugs in smuggling amounts. Not because of the police but for real, the gangs/cartels in Albania are some of the most brutal gangs in all of Europe. They are plugged into all the pharmacies. If they catch wind(which they will) of a foreigner trying to buy large amounts of drugs...they might FORCE you to be their mule. Be prepared for that.
Personally, I wouldn't touch it. You'll probably get ripped off no matter what you do.
