The Florida Department of Law Enforcement reports there were 4,700 drug arrests made in Volusia County in 2013.
In many cases, drug-related charges are not the only offense alleged. Often, drugs are discovered in the course of police investigating some other incident, which usually means defendant is arrested on multiple criminal charges.
This is also common wherever drugs and children are involved. Anytime an adult is alleged to have exposed a child to drugs or abused drugs near a child or while caring for or driving with one in the vehicle, it's probable authorities will tack on more charges - sometimes very severe charges.
