I never used it myself. My ex had plants so we had our own weed. I do not like the smell it makes me vomitting. Perhaps I smelled it too long. We saved it partly in the fridge and bread etc tasted and smelled like it also. Once in a while I buy for my sick neighbour so he will eat more and is able to sleep. I order it online and it is sealed to I never saw what it looked liked and I can not smell it. Why has your friend to buy it for you?
