On 2016 Sep 14, Peter Hajek commented:
There exists a simple test of whether the 'gateway effect' applies to humans. Over the past 60 years, the prevalence of smoking among young men in the US and UK declined about 4-fold. If nicotine use leads to increased use of cocaine and other drugs, the use of other drugs should decline as well. There is no sign of that.
