Might wanna go back and learn about the plants. Hemp can be grown in many places, and while it looks just like marijuana, it has little to no THC in it. And yeah, when I was active duty in the Navy, one of the LAST things I ever thought I'd see was being able to go into a 420 shop (happened in CO), and use my military ID (retired ID card) to get a military discount to buy marijuana! Happy days indeed! Some days, I wish I was still close to a legal state.
Well, might wanna get on the internet and do some reading. There are quite a few conditions that can be helped with the consumption of THC. Chemo patients, those with PTSD, people who suffer from epilepsy, and those with chronic muscle pain just to name a few. I know that when CO legalized it, I would go there a few times a year, and would meet lots of veterans (they would come up and say "hi" when they saw my Retired Navy ballcap). Each and every one of them said that when they were discharged, they were put under VA care for various conditions (many had PTSD), and the VA had them on a regimen of 10 to 15 pills PER DAY. When CO legalized it, they decided to try marijuana to see if it helped, and many of them were able to get off pharmaceuticals all together, and only a few of them had to remain on pills from the VA, but they were able to cut way down to just 2 or 3 pharmaceuticals per day. And, they all said that they got healthier, as they no longer had to suffer the side effects of pharmaceuticals, and the marijuana didn't give them any side effects other than the munchies on occasion.
