Thanks guys
Mr. Smith managed to get a half-decent nights sleep last night...
He has read many horror stories of these products (containing the substance "AM-2201") having withdrawals akin to crack (and that's not an understatement).
Mr. Smith went from habitually smoking a couple of joints of MJ a day, to turning to the legal weed (thinking he was doing the right thing and stopping his illegal activities). He went from smoking 2 joints of Legal weed per day to over a gram a day in LESS THAN A WEEK! Crazy horrible stuff....
It is still marketed as "100% Legal" in Australia because the manufacturers just tinker with the compounds to skirt around the law.
Anyway, Mr. Smith is getting there. He is back in the office today and is actually quite enjoying normal human contact
He has also set up a support forum dedicated to addictions to Legal Weed (and MJ - but he doesn't see that as much of an issue) - PM me if you'd like details...
Thanks again guys
