I suspect many will be skeptical of this research as it's almost become an article of faith that pot smoking is harmless and all criticism to the contrary is merely party-pooping oppression. One of the things that often concerns me about Silicon Valley in recent years has been the trend of many startups where pot smoking is part of the established culture of the company. I don't think it's a majority, but it's certainly more than I'd realized previously and it certainly seems to be a more recent trend. I'm not a vehement prohibitionist by any means. However, I've been burned by a co-founder showing up stoned to a key meeting with an investor who'd committed a 6-figure sum out of his own pocket to get the company to where it was. That was a problem. Maybe it's just me aging - I am not a big drinker nowadays, after going through the same college years everyone else did where drinking was involved in so much social activity - but over the years I've arrived at the belief that much of the time wasted stoned, by folks convinced this is making them more creative, is time that could be put to better use. Feel free to do what you want to do, sure. But reminding people that there are negative consequences is never a bad thing.
