What the Evidence Shows
The CDC outlines various health effects associated with cannabis use, including potential risks but does not equate cannabis harm directly to that of alcohol or tobacco. 2) UC San Francisco research highlights significant cardiovascular risks from chronic cannabis use, whether smoked or ingested, indicating real health concerns. 3) Comparisons between cannabis and alcohol show nuanced differences: alcohol is linked to well-documented harms including liver disease, addiction, and brain damage, while cannabis effects vary and may be less severe in some respects. 4) The Washington Post article notes limited but concerning evidence linking cannabis to heart attacks similar to tobacco but emphasizes the need for more research. 5) Northwestern Medicine discusses long-term impacts of cannabis on health without equating it fully to alcohol or tobacco harms. 6) GoodRx argues that no level of alcohol consumption improves health and suggests cannabis may be safer in some respects.cdc.govcdc.govCannabis Health Effects

Overall, while THC/cannabis is not harmless and carries specific health risks, especially with chronic use, the claim that it is "bad for your health as booze or tobacco" oversimplifies complex differences in risk profiles. Alcohol and tobacco have extensive evidence of causing severe long-term health damage and mortality at population levels. Cannabis risks are real but generally considered different in nature and magnitude. More research is needed for definitive comparisons.
This analysis reflects current evidence as of mid-2025 from multiple independent sources with some differing perspectives on relative harms.
