With prom and graduation season getting underway, now is a good time to ensure that local youth have a great time while staying safe and in compliance with the law, Essex County District Attorney Paul F. Tucker said.

For teens and parents alike, Tucker underscored the importance of being aware of the state’s social host laws regarding alcohol and legalized drugs such as marijuana. Under Massachusetts law, a social host is anyone (adult or minor) who is in control of the premises and who furnishes alcohol or allows it to be consumed on the premises.

“Some parents or teens might think, ‘It’s not a problem if it is in our controlled home environment,” Tucker said. “Bad idea.”

Permitting such consumption for guests under age 21 may result in a fine of up to $2,000, imprisonment for up to one year, or both.

Tucker said that teens should also know that, under Massachusetts’ Law, a person under 21 years of age who, in good faith, seeks medical assistance for someone experiencing alcohol-related incapacitation shall not be charged or prosecuted. Likewise, a person who, in good faith, seeks medical aid for someone experiencing a drug-related overdose shall not be charged or prosecuted for possession of a controlled substance, so there is never a reason to abandon a friend or classmate who needs help. Also, Tucker advised parents to make a proactive plan with their teens as to what they will do if they find themselves in a risky situation with which they are uncomfortable.

“Texting, calling, or moving to a safe location may be good options,” Tucker said. “As a parent, you have a major influence on the decisions your child makes.”

There are many ways for teens to throw or attend a good party without drugs or alcohol involved.

“Your future is more important than any one night or party,” Tucker said. “When you make safe and healthy choices, you afford yourself the ability to attend many more parties in the years to come.”
