The federal government on line . This website brings congress right into my favorite cattle field. Has a lot of on line scientific type studies and articles on marijuana for many different medical applications. A very cool site from Texas which is generic to gardening. I have learned a lot just reading the stuff on their site.
Cannabis is similar to tomatoes.
DC put together the movement in DC our nations capitol and this is their homepage. The site is mostly interested in drugs other than alcohol or tobacco and mixes in stories which perpetuate the myth of the recreational use of pot. Strange they would choose that name for their website. These folks are putting a lot of energy into their site. Its an overall fun site.
