Another good reason to legalise cannabis

From the BBC:

Teenagers are less likely to use cannabis in places where the drug has been legalised, a new study suggests.

Researchers at Montana State University looked at health surveys of US high school pupils between 1993 and 2017. While overall use among US youth went up, the likelihood of teen use declined by nearly 10% in states where recreational use was legalised.

For sure, we can take all these stats with a pinch of snuff. If it's illegal, are people likely to deny smoking cannabis or more likely to exaggerate (bravado and general trolling)? How do we adjust to get the true figure? Is it even relevant to anything?

Overall, the trend appears to be slightly less usage (which should keep the bansturbators happy) and lower crime (acquisitive crime and turf wars) which is the important bit, so win-win.
