The sale or possession of marijuana in the state of Maryland can lead to felony drug charges and the penalties for a conviction under those charges are very severe. For example, while the maximum sentence for a misdemeanor conviction is one year and the maximum fine is $1,000, the maximum sentence for a felony charge conviction is five years along with a maximum fine of $5,000. The amount of marijuana possessed in this case must be between 10 grams and 5 pounds. Possession of less than 10 grams of marijuana only comes with a fine of up to $100.
