Matt the Funk Reviewed by Matt the Funk on . Menthol crystals & marijuana I was having a conversation with my mother about marijuana and she said she used to use menthol crystals to make her weed menthol. Has anyone ever done this or heard of it being done? If so, how? (I've already got the menthol crystals) Rating: 5
