What Gabbard fails to address is the truth that all police officers and drug dealers know...using marijuana is the easily accessible entry or "gateway" drug into other potent, deadly, harder DRUGS.  Once marjiuana doesn't give people enough of a high, they move onto harder drugs.  Before, cigarettes were the gateway, now, it's marijuana.  Of course, no person died from using marijuana, it's because they're dying from other drugs.
