Someone recently asked, “Do you think marijuana is harmful spiritually?” Yes, marijuana can be spiritually harmful—especially for believers who seek to live under the influence of the Holy Spirit and maintain a clear mind for godly thinking and decision-making. While Scripture doesn’t mention marijuana specifically, biblical principles give us solid footing for evaluating its spiritual impact. Discernment in areas not directly addressed in Scripture requires us to align our choices with God’s revealed will for righteousness and spiritual alertness (Rom 12:1-2).
