My only advice would be either to buy organic from a source you trust, or grow your own. Growing your own is the only way to know 100% for sure because I doubt that any of the growers will let outside parties inspect their grow op.

Multiple Chemical Sensitivity Disease and MMJ Hello, I was wondering if there is anyone else out there that uses medical cannibis and is also suffering from MCS (multiple chemical sensitivity) disease. I need the cannibis for chronic pain and insomnia amoung other things, but I am really worried about any chemicals used to grow the medicene or that might be used topically on it. I am very sensitive to most chemicals and thay make me really sick. I know a lot of growers spray herbicides and fungicides and other things on the plant as Rating: 5
