One beer and one entire joint are not equivalent in levels of intoxication.
Try 6 beers vs 1 entire joint and maybe you're getting somewhere close to equivalence in level of intoxication.
Most people don't smoke an entire joint in one sitting. All it takes is about 3 or 4 puffs and that's typically enough for quite a while. That's the equivalent of about 2 beers. And I'd trust someone more behind the wheel that had a few puffs of a joint vs. someone who just drank 2 or 3 beers.
The kind of intoxication is very different between alcohol and THC. There is no way to do a 1:1 comparison as far as effects on driving ability. They each act on very different pathways, and produce different results.
Marijuana also never made anyone pass out while driving from smoking too much, but alcohol definitely can do that.
Marijuana and alcohol differ significantly when taken in large quantities. Alcohol will make a person pass out without exception. Marijuana does not specifically make a person pass out at high doses. You would need to take a low dose of marijuana to use it as a sleep aid.
