Hey, smoke shop employee here! For someone who doesn’t consume on a regular 10-25 mgs is usually a good starting place. You can always take more, you can’t take less, so it’s better to start lower and work your way up. There’s a ton of online tutorials and recipes for cooking with THC, so explore and research how to measure your dosages and you’ll be just fine!
If you mean actual smoking just get a 10$ cart from the local shop, you wont have to worry about doing too much as long as you arent just hiting it over and over again for like an hour. If you mean edibles then like the top person said 25mg is a good starting point but I would start with half, wait an hour if you dont feel anything after an hour then take the other half
