Is Marijuana Safe?

Is Marijuana Safe? 6 Is Marijuana Safe

In recent years, many states have voted to legalize marijuana, both for medical and recreational uses (Sanders, 2018). However, federal law still prohibits the use or sale of marijuana in the United States, allegedly because of negative health effects (Ripley, 2017). With the recent decision by the Justice department to crack down on marijuana distribution (Johnson, 2018), an important question is whether those federal laws have sound medical science on their side. This paper will begin to explore the specific question of whether marijuana use is harmful to health. It will explore articles that argue on each side in an effort to evaluate the quality of the reasoning of each.

Article Against the Use of Marijuana

The first article is from a web site of the Foundation for a Drug Free World, an anti-drug non-profit organization. It argues that marijuana is harmful based on several studies showing multiple sources of danger to the user and society. The reasoning presented includes key premises:

  • Premise 1: Studies show that marijuana use diminishes attention, memory, and learning.
  • Premise 2: Studies show that marijuana use increases the likelihood of traffic accidents, including fatalities.

The conclusion drawn is that marijuana use is detrimental to the health of the user and society (Foundation for a Drug Free World, n.d.).

When evaluating the quality of this argument, the premises appear strong in supporting the conclusion. The premises suggest that marijuana impairs cognitive functions and increases dangerous behavior, which logically supports the conclusion that marijuana harms health and safety. However, for these premises to definitively support the conclusion, one must assume that there are no circumstances where the negatives are outweighed by benefits. For example, medical cases where marijuana alleviates severe symptoms—such as chemotherapy side effects or glaucoma—may justify its use despite these risks. Such cases highlight that the premises, while valid in general, do not account for all contexts, and therefore, the argument lacks universal validity.

Further critical evaluation reveals a weakness: the article provides no direct citations or references to the studies supporting its premises. It directs readers to contact the organization for sources, which diminishes the argument's credibility. The lack of transparent support reduces the strength of its reasoning and leaves open questions regarding the empirical evidence behind its claims.

Article Supporting the Safety of Marijuana Use

The second article comes from Americans for Safe Access, an organization advocating for the legalization and safe use of marijuana. This source argues that marijuana can be used safely and healthfully, citing a variety of studies. Its key premises include:

  • Premise 1: A report from the Substance Abuse and Mental Health Services Administration states that there has never been a death recorded from the use of cannabis (Americans for Safe Access, 2018).
  • Premise 2: Scientific research has shown that marijuana is safer than many foods and legal medications (2018).
  • Premise 3: Research indicates no negative effects on lung function for moderate users (2018).
  • Premise 4: Marijuana has been shown to be less addictive and less prone to abuse than many legal drugs (2018).
  • Premise 5: The side effects of smoking marijuana are relatively minor and can be mitigated with precautions (2018).

The conclusion states that marijuana use is relatively safe compared to other medications.

Critical evaluation shows that these arguments are compelling, addressing major concerns about safety. Nonetheless, limitations exist. For instance, some studies cited acknowledge potential long-term cognitive effects, such as decrements in learning and memory among chronic users (Grant et al., 2003). While the article emphasizes safety, it does not dismiss the possibility of adverse effects, making its conclusion more cautious in scope.

Similarly, the support for its premises relies heavily on high-quality studies, though citations are not directly provided on the webpage. The references are accessible via links requiring membership or registration, which might undermine transparency and independent verification. Despite this, the overall strength of the argument remains considerable, assuming the cited research is credible and accurately represented.

Both articles provide persuasive points but also contain limitations regarding evidentiary support and scope. The anti-marijuana source emphasizes risks but lacks direct references, weakening its conclusiveness. Conversely, the pro-marijuana source presents a well-rounded argument but admits some potential negative effects, preventing overgeneralization of safety.

Conclusion

Evaluating these arguments reveals that while there is evidence suggesting marijuana can pose health and safety risks, there is also substantial research indicating it is relatively safe when used responsibly. The strength of each argument depends on the quality and transparency of their supporting evidence. Reflection on both sources highlights the importance of considering context, such as medical necessity versus recreational use, in assessing marijuana's safety profile. Until more definitive and comprehensive scientific research is available, the debate remains nuanced, requiring cautious interpretation of existing findings.
