The problem is not you smoking marijuana or consuming it. I think it’s acceptable for Christians to use it. The problem is drunkenness meaning getting too high. Drunkenness is always condemned in the Bible but the use of Cannabis is not wrong go ahead if you want to use and be a Christian, it’s just don’t get too high or what the Bible calls drunkenness. The use of alcohol for Christians is not wrong either it’s the overconsumption of it that is sin. It’s not a persons sins that sends someone to hell, it’s their rejection of Jesus Christ. There will be moral Christians and immoral Christians in heaven because morality or being good is not why a person goes to heaven. If we could go to heaven because we are good then why did Jesus have to come and die. It’s because no one is good by Gods standards. Accepting Jesus slaps a one way ticket into your pocket for Heaven. Were you a prostitute? Jesus died for that you can still go to heaven. Were your an anger and murderous person? Jesus died for that. Are you a bad person or maybe you think your a good person, your goodness or badness is not why someone goes to heaven or hell it’s your acceptance or rejection of Jesus as Lord and Savior that sends someone to Heaven or Hell. Do you want to be saved? Reach out and accept Jesus as your Lord or your King. Whoever calls on the name of the Lord will be saved the Bible says
