Delta-8 THC is very viscous to solid the colder it gets. At room temperature and higher it turns to a honey, then maple syrup, and finally almost water like viscosity. So if you want to use a syringe, make sure to warm up your syringe and delta-8 THC distillate or shatter first. If you want to scoop some with an object, then having it room temperature (or cooler for breaking apart) will probably be prudent.
One of the easiest ways to try it if you already smoke or vaporize bud/flower is to add some on top and burn it. Be careful though, as you may notice a denser smoke/vape!
The most direct method is to vaporize delta-8 THC in a glass dab rig with an enail or butane torch. A dab rig refers to, essentially, glass bongs designed for oil and wax. There are also fully electronic, portable dabbing devices.
Vape cartridges are probably the easiest and most popular way to consume delta-8 THC. Flavored with terpene recipes to produce flavors like Wedding Cake, they can be a delicious tasting way to try Delta-8 THC and enjoy out and about. Just remember to have a pen battery so you can power them!
Edibles like gummies or tinctures are another easy way to ingest delta-8 THC, without having to inhale it! A great choice for people that have respiratory conditions.
