Cannabis WD effects are very real. After trying to quit earlier this week I experienced cold sweats, accompanied by almost 3 hours hugging the toilet bowl throwing up. This was coming off a 1-1.5gram-a-day wax habit. In the past quitting was very easy for me and I had no such WD, and tbph I laughed when others complained of cannabis WD, having gone through opiate and GABAnergic WDs before, but now I'd say a long-term, hefty habit can produce WD's somewhat comparable to coming off a mild hydrocodone dependency (10-20mg/ day for a relatively short period of time). Of course, it's mostly of psychological origin, but the results can be very unpleasant. The good news is that after about a week they subside, and tapering seems to help as well.
