Guan, pronounced 'gwaaaaaan', is a coloquial term used in place of the words marijuana or cannabis. In the UK, it is a class 'C' drug, though is of late often mistaken as being legal by many youths. The drug is usually taken via smoking, which usually involves rolling a cigarette with rolling papers and rolling tobacco, adding ground guan to the cigarette, and smoking the end result.
