I've seen videos of people heating with a lighter. I usually use a torch lighter or my husband's cigar lighter. Really the easiest thing to make that's also super popular is weed cheezits..i usually make plain ones with cbd and hot& spicy ones with thc. Melt butter with hash slowly so it's fully mixed, drizzle it over a big bowl of cheezits, put them in a single layer on a cookie sheet and bake until they're mostly dry. Let them cool before you put them in a container. You can do the same with anything like that - honey nut Cheerios are good. Word of caution - if you eat weed cheezits and get the munchies, you will want to eat the rest of the cheezits and that can end badly - like getting too high, going to work, and then spending most of your shift taking bites off a giant chunk of cheese and a summer sausage when you think you're being sneaky with it. Always keep a fresh box of cheezits on hand!!
