    My brother says he smokes because he gets headaches every day. I think it’s the other way around. That or it’s just his excuse.

    A reputable psychiatrist and addiction specialist once told me that cigarettes are more of a gateway drug than marijuana…makes sense IMO.

    Don’t believe this propagandist. The Gateway Hypothesis (GH) is still strongly supported by evidence, see drugabuse.gov. A 2015 study found 45% of cannabis users actually go on to use other illicit drugs.

    The war on drugs is such a farce.

    I always said “Marijuana Wasn’t the gateway… Dealers were the gateway… the guy that has the weed always had Other things.. Blow.. Speed..MDMA and Pain Killers … usually “

    I’ve only ever smoked cannabis. Never even tobacco. I rarely drink also. Definitely not a gateway for me.

    I remember my health teacher saying you should *never* do weed, even recreationally, as u can become addicted. Then she said casual and social drinking are perfectly fine… ????

Open source AI is booming, according to Hugging Face CEO Clem Delangue. The company has grown into something like a GitHub for AI in recent years, where AI builders can share and download open models and datasets, now used by roughly half the Fortune 500. Delangue has seen the same story play out again and again: companies start out on frontier APIs, but as they scale, the costs push them towards open source models.

On this episode of TechCrunch’s Equity podcast, Rebecca Bellan talked to Delangue about why the open vs closed source fight matters in the wake of Anthropic’s halted Fable release, and why he’s worried about the possibility that a handful of big companies could end up controlling everything.
