Marijuana Use: Sin Or Personal Choice?

The legalisation of marijuana in several US states has sparked a debate among Christians about whether or not using the drug is a sin. While the Bible does not explicitly mention marijuana, some Christians argue that the drug's mind-altering effects are comparable to drunkenness, which the Bible warns against. Others argue that the legal status of marijuana in their state means it is no longer a sin, and that morality does not derive from laws.

Marijuana's effects on the brain and body

Marijuana, also known as weed, grass, or pot, is a mind-altering substance that comes from the cannabis plant. It is one of the most used drugs in the U.S., especially among people aged 18-25. The main psychoactive ingredient in weed, THC, travels into the bloodstream to the brain. Once there, it connects to cannabinoid receptors on nerve cells, which control functions such as hunger, memory, and alertness.

Marijuana can have a variety of effects on the brain and body, including:

Short-term effects

• Altered time perception
• Impaired thinking, memory, and body movement
• Increased appetite
• Feelings of happiness or relaxation
• Irritability or restlessness
• Hallucinations
• Increased heart rate and respiratory problems

Long-term effects

• Harms to lung health, including inflammation and chronic bronchitis
• Mental health conditions, including an increased risk of psychosis and schizophrenia
• Gastrointestinal problems, such as cannabinoid hyperemesis syndrome
• Increased cancer risk, particularly in the head, neck, or throat
• Negative effects on cognitive functions, including learning, memory, attention, and processing speed
• Addiction or cannabis use disorder

The impact of marijuana on the brain and body depends on various factors, including the amount and potency of THC in the cannabis, the method of ingestion, frequency of use, age of first use, and whether other substances are used concurrently.

The legality of marijuana

United States

In the United States, the legal status of marijuana differs from state to state. As of 2025, marijuana use and possession have been decriminalized in 24 states for recreational purposes, with Minnesota being the latest addition. 39 states permit its use for medical reasons. However, at the federal level, marijuana is still classified as a Schedule I drug under the Controlled Substances Act, deemed to have a high potential for abuse and no accepted medical use. Despite this, federal law enforcement against possession, cultivation, or intrastate distribution is generally not enforced in states where marijuana has been legalized.

Religious Perspectives

From a religious perspective, the topic of marijuana legality is nuanced. Christians, for example, have historically argued for the prohibition of marijuana use, citing Romans 13:1, which emphasizes submitting to governing authorities. However, with changing laws and the increasing legalization of marijuana in certain states, Christians are now engaging in more comprehensive discussions about the morality of its use.

Biblical Perspective

The Bible does not explicitly mention marijuana or provide a clear directive on its use. However, it does offer principles and commands that can guide Christians in their decision-making. For instance, the Bible emphasizes the importance of sober-mindedness and self-control, which could be relevant considerations when evaluating the impact of marijuana use.

In conclusion, the legality of marijuana differs across jurisdictions, and it is essential to refer to the specific laws and regulations in your region. The topic also intersects with religious and ethical perspectives, adding further complexity to the discussion.

The Bible's silence on marijuana

The Bible does not explicitly mention marijuana, and this silence has led to differing interpretations of its stance on the substance. While some Christians have historically argued for the prohibition of marijuana use, citing verses such as Romans 13:1, which instructs believers to obey governing authorities, this argument has been challenged by the legalisation of marijuana in an increasing number of states.

The absence of specific biblical directives regarding marijuana has prompted Christians to consider analogous issues addressed in Scripture, such as alcohol consumption. The Bible warns against drunkenness and surrounding oneself with drunkards, and some Christians have drawn parallels between the intoxicating effects of alcohol and marijuana, suggesting that similar cautions could be applied to marijuana use.

However, others have distinguished between the two substances, noting that alcohol can be consumed in moderation without leading to intoxication, whereas a much lower dosage of marijuana creates a state of intoxication. This distinction has led some Christians to conclude that even a small amount of marijuana use could be considered a sin.

The discussion around marijuana use among Christians is complex and multifaceted, taking into account not only biblical teachings but also individual experiences, motivations, and the legal landscape surrounding marijuana use.

Marijuana as a 'gateway drug'

The idea of marijuana as a "gateway drug" is controversial. Research suggests that people are more likely to use cannabis before moving on to other drugs. However, the research is not conclusive, and even studies that show a link suggest only a very weak one.

Some studies have found that individuals who use cannabis before using other drugs may have a higher risk of developing a substance use disorder. For example, a 2021 study found a higher likelihood of opioid use and misuse among people who use cannabis. However, the study authors advised that the quality of the evidence is low, and it is not possible to conclude that cannabis use causes the use or misuse of other drugs.

Other studies have found that cannabis users have a higher lifetime risk of misusing other drugs. A 2020 study found that teenagers who use cannabis are 104 times more likely to use cocaine than those who do not. However, there were significant differences between the two groups that predated their cannabis use, suggesting that other factors may explain the use of both drugs.

Animal studies have also indicated that early exposure to cannabis could alter the brain's response to dopamine, a chemical that drives substance use disorder. It could also make the brain respond more strongly to other drugs. However, it is unclear if cannabis has the same effect on humans.

While the research is inconclusive, it is important to note that even if cannabis is a gateway drug, banning it does not appear to be an effective solution. In fact, some studies have found that criminalizing cannabis increases its availability and use and puts more potent forms of the drug on the market.

The morality of marijuana use

Marijuana has been used for medicinal and recreational purposes for thousands of years. In recent years, and with the legalisation of marijuana in several US states, the morality of its use has become a topic of discussion among Christians.

The Bible does not explicitly mention marijuana, and so Christians must use analogical reasoning to draw conclusions about whether smoking weed is a sin.

Some Christians argue that because marijuana is legal, it is therefore morally acceptable. However, this argument falls down when considering that many things that are legal are still considered sinful.

Others argue that because marijuana is a plant created by God, it is therefore good. However, this does not necessarily mean that God intended for it to be smoked.

A more convincing argument is that marijuana should be treated in the same way as alcohol. The Bible warns against drunkenness, and the dangers of losing the ability to make sound judgments. This can also be applied to marijuana use, which can cause impaired judgment and cognitive functioning.

The Bible also talks about the importance of being sober-minded and having self-control. Smoking marijuana could be considered a violation of these commands.

Ultimately, the morality of marijuana use is a complex issue that Christians must navigate using their own judgment and biblical teachings. Some Christians may choose to abstain from marijuana use, while others may use it in moderation, always being mindful of how it affects their relationship with God and their ability to make decisions.
