The Bible doesn’t mention tobacco or marijuana, but its principles still apply. Smoking is sinful when it becomes an addiction, breaks the law, or harms others. Marijuana raises an additional concern, because it impairs the clear, sober mind God calls us to have. Christians should honor God with their bodies and stay alert to spiritual danger.
When Smoking Is Sinful
Many Christians grew up assuming any smoking was sinful. The Bible doesn’t address tobacco directly, but several principles make it clear when smoking crosses the line. The first is addiction.
1 Corinthians 6:12 “I have the right to do anything,” you say—but not everything is beneficial. “I have the right to do anything”—but I will not be mastered by anything.
Nicotine is highly addictive. If you need it to get through the day or reach for it every time you’re stressed, it has mastered you.
Smoking is also sinful when it breaks the law, such as underage use. Even if we don’t like a law, God calls us to submit to authority unless it requires us to disobey him.
1 Peter 2:13-14 Submit yourselves for the Lord’s sake to every human authority: whether to the emperor, as the supreme authority, or to governors, who are sent by him to punish those who do wrong and to commend those who do right.
Finally, smoking is wrong when it harms others: smoking while pregnant, exposing children to secondhand smoke, or ignoring a spouse’s wishes. Husbands are called to love their wives sacrificially (Ephesians 5:25).
Your Body Is a Temple
Some believe all smoking is sinful because it damages the body. Scripture does call us to honor God with our bodies.
1 Corinthians 6:19-20 Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies.
If that’s your conviction, it’s worth taking seriously. But be consistent. The same principle applies to what we eat and drink, how we exercise, and how we rest. Honoring God with our bodies covers far more than tobacco.
Marijuana and a Sober Mind
Marijuana raises a different concern. Research shows that it directly affects brain function, including memory, attention, decision-making, coordination, and reaction time. Heavy use, especially among young people, has also been linked to anxiety, paranoia, and other mental health problems. Scripture repeatedly calls believers to keep a clear mind.
1 Peter 5:8 Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour.
Peter knew what it was like to be overconfident and fail (Mark 14:29-31). He urged believers to stay prepared.
1 Peter 1:13 Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revealed at his coming.
Even where marijuana is legal, using it to get high dulls the very alertness God calls us to have. Interestingly, Jesus refused wine mixed with myrrh, an ancient painkiller, while he was on the cross (Mark 15:23). You can read more in Is It OK to Smoke Marijuana?
The Takeaway
Smoking tobacco or marijuana is sinful when it becomes an addiction, breaks the law, or harms others. Marijuana also impairs the sober, alert mind God calls us to have. If the Holy Spirit is convicting you, even about occasional use, listen and obey.
