I also witnessed a Niece who had a brain tumor and pot really helped relieve her pain, also her father a Dentist developed a brain tumor about 4-5 years after she died. I have great sympthy for those that truly need it for pain. I have no feeling for those that want to abuse it and/or get Doctors to fake perscriptions so they can bring it to the general public. My thoughts go out to those suffering and I only hope we can find a way to control it's use. We also have to think of the under 21 crowd who when using bring potentially terible problems to the unborn or the one that is subject to addition and it causes them to renew their addictions. In the case of the niece my sister went out at night in Washington, DC and got it on the black market from dealers. It is the junkies and the loose Dr's who are stopping the usage for the sick.
