1. It's still too early to tell if Michigan's new marijuana law is affecting DUI rates. There haven't been any major studies conducted yet that would give a definitive answer.
2. However, there is some anecdotal evidence that suggests that the law is having an impact. For example, there has been a decrease in the number of arrests made for driving under the influence of marijuana.
3. It's possible that this is because people are now more likely to smoke marijuana in private, rather than in public, where they could be more likely to get caught.
4. Another possibility is that the new law is actually making it easier for people to get away with driving under the influence of marijuana. This is because the police may not be as likely to pull someone over if they suspect that they are driving under the influence of marijuana.
5. Only time will tell if Michigan's new marijuana law is actually having an impact on DUI rates. However, it's clear that more research is needed in order to get a better understanding of the issue.
