Would that be considered a massive amount to ingest compared to what you might get from incidental expose to second hand smoke?
It doesn’t really matter with second hand smoke, does it. Any amount is considered dangerous with tobacco. The same standard will apply because the risk of permanent brain damage is just too great a burden to bear.
The complaints and threats of law suits will influence landlords and community associations. No one will want to be responsible and the marijuana smokers will be put in the position of proving a negative.
Not fair? Not right? Maybe not, but that’s the way it’s going to be. The war on drugs will be endless, whether legalized or not.
