Mr. and Mrs. Shrooms have an actual certificate/license to grow, sell, and facilitate therapeutic mushroom trips. Either way, if you are interested in tripping mushrooms in Negril (or anywhere else in Jamaica) just google Mr and Mrs Shrooms and call them.

I can say from personal experience, their products are exactly what they say they are, you can also tour their farm and see exactly how they grow them, the lengths they go to in order to keep them safe and contamination free, and you can choose to take a guided trip with them there. All safe, all legal, all a lot of fun and all therapeutic. I basically took some of every product they make, and a lot of certain products they make. Trust me, they are the way to go if you want to trip in Jamaica.
