Perhaps the drive to ban drugs is misplaced. The war is being lost anyway. Since the 1960s research on psychedelic drugs has been frowned upon. However, recent findings show benefits from imbibing these chemicals which come mainly from mushrooms.
Psychedelics alter perception so that an individuals sees strange things that are not there. A side benefit is an improvement in mood. Anxiety and depression tend to disappear. Research in the US and Europe is really taking off. Oddly, although the drugs have been banned they are not addictive.
Australia is not following the lead. It is still stuck in the past with talk about psychedelics being hushed up. A further problem is that chemicals derived from mushrooms and cacti are not patentable. There is no big money in it.
The harm done by regular intake of psychedelics is near zero. Quite different from the common belief. Many of the elderly suffer from psychological problems. If these can be solved by putting the aged into a better state of mind a lot of good will be done.
