Colorado man shoots himself after eating marijuana candy Video by ktnv.com By Joyce Lupiani. CREATED Mar 26, 2015 A 23-year-old man from Colorado killed himself while on a family vacation, and his mom is blaming it on edible marijuana. According to CBS Denver, Luke Goodman and a cousin purchased $78 worth of marijuana edibles on Saturday. Goodman reportedly consumed several pieces of peach tart candy that contained 10mg of the active ingredient in marijuana. The recommended dose is just one piece of candy. Several hours later, Goodman's cousin said that he became "jittery" and "pretty weird and relatively incoherent." When family members left him alone, Goodman retrieved a gun that he usually carried for protection and shot himself. Goodman's mother is blaming the drugs. She says her son had no signs of depression or suicidal thoughts. “It was 100 percent the drugs,” she said. “It was completely because of the drugs — he had consumed so much of it.” His cousin also says that he believes the drugs are to blame. This is not the first death in Colorado to be blamed on marijuana. A 19-year-old Wyoming college student jumped to his death from a Denver hotel balcony a year ago. His friends said that he was also rambling incoherently after eating a marijuana cookie. Richard Kirk of Denver is facing murder charges after he shot his wife last year. His wife called 911 before she died and said that her husband had eaten marijuana candy and prescription medication and was hallucinating. Goodman's mother says edible marijuana should be removed from store shelves. Recreational use of marijuana became legal in Colorado in November 2012.
