Legalizing marijuana at the federal level could potentially generate significant tax revenue for the government, which could be used to help address the national debt. According to a report from the Congressional Budget Office, legalizing marijuana at the federal level could generate an estimated $8 billion in federal revenue by 2027.

However, it is important to note that while marijuana legalization could generate revenue for the government, it is unlikely to be a significant solution to the national debt on its own. The current national debt is over $28 trillion, and even with the potential revenue from marijuana legalization, it would only make a small dent in the overall debt.

Additionally, the economic impact of marijuana legalization is complex, and it is difficult to predict with certainty the effects on the economy, including potential job creation or other economic benefits.

Overall, while legalizing marijuana at the federal level could potentially generate revenue for the government, it is unlikely to be a comprehensive solution to the national debt.
