Legal Question in Criminal Law in Michigan

Possession of Marijuana is a 1-year offense. It is too serious of a charge to be a "ticket" crime. It is prosecuted via a complaint issued by the prosecutor. Some prosecutor offices will issue a Possession of Marijuana with only the cop's field test result showing that it is in fact that drug, but others want actual lab reports. Charges in the latter jurisdictions, though, don't get issued as promptly because it can take a month or more for lab reports to come back on drug testing like this. Personally, I think that the "issue based on field test" option is better because (a) only cases that are scheduled for trials will have formal lab testing; (b) 95% of these cases plead out, so you're lightening the load in a crime lab that's already overloaded; (c) lightening the load like this can help speed up testing on other cases.
