According to the New Jersey Cannabis Regulatory Commission, it’s against the law for consumers to take their marijuana purchase across state lines.

Individuals are allowed to purchase one-ounce gifts of marijuana, provided the recipient is at least 21 years old. However, state regulators warn individuals who gifted the marijuana can’t receive compensation in return.
