Possession of Cannabis or possession of marijuana under 20 Grams is a misdemeanor charge with the potential penalties of 1 year in the county jail, 1 year probation and a fine of 1,000 dollars. There is also a one year suspension of your driver's license if convicted.
I am a former Seminole County Prosecutor and have handled many drug charges from both sides of the law. Now as a criminal defense attorney since 2005 I have had the pleasure of representing many clients who find themselves charged with a drug offense. Drug offenses are serious and can have severe penalties such as jail time, probation, a criminal conviction and the loss of your drivers license.
In Florida someone convicted of a drug charge can lose their license for a period of 2 years through the court and or DMHSV. This is viewed as an harsh consequence by many in the legal justice system. The DHSMV can suspend your license even if the Judge does not order it as a part of a sentence.
