what is a class d substance

A Class D substance generally refers to a category of controlled substances that have a lower potential for misuse and addiction compared to higher classes (like Class A, B, or C). In the context of Massachusetts law, Class D substances include drugs such as marijuana (more than one ounce), barbiturates like phenobarbital, barbital, and substances like ethchlorvynol and meprobamate. These substances may be available by prescription but are controlled due to their potential for misuse. Penalties for violations involving Class D substances typically include up to 2 years in jail and/or fines ranging from $500 to $5,000. Possession of about an ounce or less of marijuana is not considered a crime, but possession of more than that may be classified under Class D with associated legal consequences. In summary, Class D substances include certain depressants, barbiturates, marijuana over specified quantities, and related compounds, and they are regulated with specific penalties for illegal manufacture, distribution, or possession.
