BBC NEWS | Health | 'Month of cannabis terrified me'

Fuck the BBC, they are taking a very biased stance on it again. What they are saying is generally true about some of the stronger skunk varieties, but what this guy here is saying is complete tosh.

"Martin Barnes, chief executive of charity Drugscope, said that most evidence about the potential health harms of cannabis had been gathered using lower-strength cannabis varieties.

"The average potency of cannabis available in the UK has increased, and while it is intuitive that greater harm potentially will arise from stronger forms of cannabis, people shouldn't assume that only the stronger types are harmful."

Most of the BULLSHIT you hear about it IS based on lower strength varieties but he fails to also mention the fact that many of these poor quality forms of hash and weed are cut with all sorts of crap, contain large amounts of chemicals used to grow it and have THC balances which are probably not as good for you as better quality shit.

I have seen a few trailers for this and I think it should be quite good as she does not appear to be one of the "Oh God my child is smoking Skunk which is 500 times more potent than when I was a teenager brigade" Cheers NCM Rating: 5
