I think there's two main reasons for this:

1. There has been a flood gate of legalization around the world, but there has been zero enlightened culture and society regarding the use of Marijuana. People don't know how to use it. They don't know the risks, they don't know how to unlock the benefits.

2. There has been an increasing move to extracts and gmo strains that are much much more potent than our bodies have ever been accustomed to.
