First and foremost, you can't store delta 8 disposables or vape pens in your checked luggage. These products must come on the plane with you, either in your carry-on or personal storage.
TSA allows passengers to bring electronic cigarettes and similar devices (vaporizers, vape pens, mods, atomizers, and electronic nicotine delivery systems) through airport security as a carry-on. What is this? However, these devices are prohibited in checked baggage.
Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should be placed in your checked bags if possible.
If you're trying to fly with edibles, stash them in a resealable fruit snack or gummy bear pouch — something that's also not a permeable plastic ziplock bag. If you use a ziplock bag, your edibles will scan as orange, which alerts TSA of “biological material.” Fortunately, most vape pens can pass as eCigarrettes.
Depends on the agent you get at the check-in desk and how overweight your bags are. Generally, they'll let you slide by a pound or two, but they're not obligated to. If you're over by more than that (or if you get someone who is being overly strict) they'll give you the option of paying extra or removing something.
Battery-powered electronic smoking devices, such as “e-cigarettes, e-cigs, e-cigars, e-pipes, e-hookahs, personal vaporizers, electronic nicotine delivery systems,” can be brought as carry-on items only. They may be carried by passengers or crew members and are for personal use only.
