1. Unfortunately, too many people are irresponsible idiots. I don't mind people smoking, but if you drive while high, you will be impaired.
2. I don't think that pot impairs driving as badly as alcohol, but that doesn't really matter, as both certainly DO impair driving ability to some extent.
3. It's funny that different posters seem to think that pot is stronger now, or that it was stronger in the past
4. One thing to keep in mind is that there may also be an increase in tourists to the states with legalized weed, which could have something to do with the increase in crashes, too.
5. Someone said something about people being unlikely to drink. Really? That argument is pretty out there. People have been drinking alcohol for thousands of years and show no sign of stopping.
If you get high, don't drive. You might not be as impaired as a drunk driver, but you are still impaired.
