Read this story a couple of days ago and it simply didn't pass the sniff test, not least of all had to do with the NCPIC as a story source. NCPIC is a govt funded anti-cannabis propaganda spin factory, co-located with UNSW. First, the quantity. If you're smoking cones, you'll go through about a gram a day (3-5 cones). I could only see an oz a week if you're rolling several fat spliffs a day. Second, the '$150 for 1-1.5oz/week' tale- my opinion meets consensus in this thread- we'd all like to meet that dealer selling 1.5oz for $150. Not in Sydney, that's for sure. Let's give this joker the benefit of the doubt and say he was misquoted- and was smoking 1.5GRAMSper week. If he was buying off the street in KX, he might pay $50 for a .5g bud, enough to roll a joint or have a few cones. A frugal smoker could make that last a couple of days. If he wants to get high every day, he might indeed spend $150 by buying three $50 buds at the worst price possible each week. However, if he's going through 1.5g/week, he's a pretty light smoker. Third, as cybergenesis notes, any withdrawal symptoms (certainly those described in the news item) would be easily attributable to tobacco. Cannabis use cessation doesn't produce a physiological withdrawal. It can certainly produce a psychological withdrawal, though. Mind, a person who is accustomed to having a newspaper delivered each morning may experience symptoms of psychological withdrawal when the paperboy is in bed with the flu. Any way you look at it, NCPIC have found a worst case and blown it way out of proportion. Rather shocked Jan Copeland didn't manage to work 'cannabis induced psychosis' into this tawdry sad-sack tale. Copeland is a straight 'Reefer Madness' type zero-tolerance conspiracy theorist and should be dismissed with contempt and laughter.
