How are controlled substances classified in Michigan?
Depending on the type and quantity of the drug, a person could be looking at many years in prison along with exorbitant fines. Controlled substances are broken into different drug schedules by the federal government based on how addictive a substance is and how likely it is to be abused.
The state of Michigan uses the same classification determining drug penalties. There are five different drug schedules, with Schedule I being the most problematic and Schedule V being the least. This guide explains the differences between schedule and lists common drugs found within each.
Schedule I
Along with an increased likelihood of dependence, Schedule I drugs are considered to have no medical applications. Heroin, ecstasy, LSD, and methaqualone (which is a sedative) are all classed as Schedule I drugs. Despite it being legal in some states, including Michigan, marijuana is also considered a Schedule I substance on the federal level.
Schedule II
While Schedule II drugs also have a high potential for dependence, they can be used in controlled medical settings for sedation and pain relief. Schedule II drugs include cocaine, methadone, Adderall, fentanyl, and oxycodone.
Schedule III-V
Substances included in Schedules III through V are considered a lower risk in terms of abuse potential, but they can still cause problems in users. They include:
- Schedule III -  Ketamine, codeine, and anabolic steroids fall into this category.
- Schedule IV -  Antianxiety medications like Xanax, Valium, and Ativan are all Schedule IV. Sleep aid Ambien is also included. 
- Schedule V -  Some Schedule V substances can be purchased over the counter in drug stores, while others require a prescription. Over the counter medications such as cough medicine are considered Schedule V, as are nerve pain medications like Lyrica.
