Cannabidiol, or CBD oil, falls under Michigan's existing medical marijuana laws, according to the Michigan Department of Licensing and Regulatory Affairs.
In an advisory bulletin released Thursday afternoon, the department said CBD derived from marijuana is defined as marijuana under state law.
The purchase, sale or possession of CBD oil must therefore be in compliance with marijuana licensing laws, the department bulletin concluded.
CBD oil can come from either marijuana or hemp, both of which are a form of cannabis. Under Michigan law, hemp is only legal when used for research purposes.
Supporters of the substance say CBD can be used to treat various medical ailments and does not cause the user to to get high.
