With so much talk around medical cannabis, legalisation and how "safe" it is as a recreational drug, it is important to remember that, for many, the drug can wreak havoc on their lives.
One such person who can attest to the impact is Dave Chant, who was our guest last weekend on the Nutters Club.
Cannabis addiction was a problem for Chant for most of his adult life. Like many, it's a tale of gradually slipping from social use to increased daily use to needing to be stoned every minute he was awake.
Many people will, of course, try to tell you that cannabis isn't addictive. Some people make the distinction between physical and psychological addiction, where drugs like nicotine, alcohol and methamphetamine (or "P") are physically addictive, and cannabis isn't.
This is a false and incredibly unhelpful distinction. As is the idea that cannabis is a "safe" drug.
