I find this topic interesting and have a question, sorry if it has already been asked!
What is the best way to take it? As smoking is a no no for crohns what is the next best method of consumption? Brownies?
I live in the UK and think it is a farce that if you want to explore this treatment method you have to buy substandard product from some dodgy bloke in the street!
Vaporizing or eating it (after it's been prepared properly) are the best methods of delivery.
If your only option is the street then I'd grow it myself in a closet and in secret. It's easy, relatively cheap passed the first time capital investment (which can be small) and you'll get quality product.
One of the largest marijuana seed bank IN THE WORLD is based in the UK, so you'd get your seeds delivered to you locally essentially.
