About 70% will have tried cannabis and about 50% will have tried tobacco. In fact, the trends are declining right now.
It's interesting that using a public health-centred campaign and honest education, we have reduced tobacco rates without having to criminalize anyone or criminalizing our youth. But we've had to do that, and we're having no success is reducing youth use of cannabis.
It is also worth mentioning that U.S. states that have legalized medical marijuana are now finding a decline in youth use of marijuana, which is interesting. We find the same thing in Holland as well.
