I find this statement highly amusing, as (1) I use cannabis regularly without issue, (2) I've done well in both academic and professional spheres, and (3) both of my parents know and are perfectly fine with my responsible usage.
Perhaps you mean that no parent wants their young child/teenager to use drugs? No one in this thread (or anyone at Meadow) is advocating for that, we are specifically discussing adult use.
If we can take anything away from this extrapolated conversation, it should be that it's important to become educated and informed about topics highly susceptible to misinformation.
