It really depends on the person and situation, if you are a new smoker you are more likely to be paranoid. If your parents are strict or you’re somewhere you’re not supposed to be you will be paranoid. If you find that weed makes you anxious but you still want to partake do it in a comfortable environment. If your parents are strict go to a close friends house or do it when they are at work. Smoke in your back yard so there’s no chance of it smelling. If you can do it while they are sleeping. Remember to breathe and wash your hands and change your clothes. If you do smoke in your room, close the vent and shove a towel under the door, open your window and try to smoke out of it, keep it so only your head is sticking out then open it fully when you’re done to let the room air out. Incense and perfume will raise suspicions. If you can, take a shower and make sure it is hot, leave the door open and this will air everything out and you should be good to go. Be safe and careful!
