Your drug use does not look catastrophic. The reckless driving does not look terrible either. Neither is good... but, like you said, in many departments, neither will be an automatic DQ.
In any event, lots of time is your friend. The more time you can puyt between these incidents without having any further incidents, the less harm they will do to your background.
With that said, keep a very important thing in mind: While not being DQing factors, they are certain to weigh you down against the many other applicants who do not have these black marks on their records. I would go for a bachelor's as an extra bolster to your application. Hell, military wouldn't hurt, either... the thing about the military is that it is never worth it unless you truly want to do it on its own merit (if that makes any sense).
The best way to look at being competitive v. being qualified is by looking at men when they go out to a club on a Saturday night. We all know the standards may be pretty low as to who you would take home when closing time comes around. Let's call that the "qualified" applicant. We'll call the "most competitive" applicants the girls that this guy is hitting on and asking for numbers early in the night. While the girl at closing time may meet the standards, she is probably a far cry from the girls he hits on while it's early and he is sober.
The key to getting a job offer is to not be the girl standing there at closing time, hoping to still get asked out.
