As much as people may wish to help you with your quest i am sure talk of MOM is still a NO NO on this site. So you probably will not find out any required information. Every man and the dog seems to smoke in england so you may be able to easily find what you are looking for in this country, however with the grit weed and the sprayed weed that is present at the moment chances are you may not be happy with the end product. I assume this is why you look for other ways.

All i can say is there are plenty of mary jane forums which do not take the medical and ethical approach where you may stand a better chance of finding what you want.
