There's also the excuse they use that "a lot of" marijuana is dried improperly and can be contaminated with mold spores that you inhale when you smoke it. Not so dangerous for relatively healthy people, but it can cause serious problems for immunosuppressed transplant patients; thus, having a habit of smoking is not good for a transplant patient.
I believe it is legal in Colorado whether medical or not! They have legalized it for all!!! I could be wrong though.God Bless,lmunchkin
