Marley like all rastas didn't mix with tobacco,pure weed.Cannabis is good for certain illnesses,its not going to cure everything however.I did meet a guy,a scientist who grew for the government in the UK,he hinted that it had cured his cancer,but I guess we will never know the true story,its all a grey area due to the illegality,but anyone wanting to try the oil,and I know someone at the moment who is trying it for cancer,its got to be full-spectrum or your wasting your time,and with that sort of illness time isn't something you can afford to play with.
