Marijuana legalization will likely result in increased marijuana consumption with uncertain social and health impacts. This thesis looks to share user perspectives on marijuana, specifically addressing how users represent marijuana risks, benefits, and uncertain or unknown dangers. Data were collected from an online social-media forum that initiated the discussion by prompting readers to reflect on marijuana risks in a context of growing accolades concerning its benefits. Grounded theory and thematic analysis were both utilized to identify consistent themes or patterns across user comments. It was found that users identified both benefits and risks of marijuana, while some users had disputes about certain known risks (such as impaired driving) or uncertain or unknown dangers (such as reduced dream activity). Despite disagreements about the degree of risk associated with a particular activity (such as driving and dreaming), this thesis found risks and benefits were discussed in relatively narrow ways that suggest more education is needed around the full spectrum of the effects of various strains, including benefits, risks, and uncertainties.
