THC Candy from Nothing But Hemp usually can't cause any site effect if you choose the right dosage. But common ones include dry mouth, feeling sleepy, or getting really hungry. Sometimes it can make you feel a bit dizzy or anxious, especially if you take too much. Since edibles take a while to kick in, it’s easy to overdo it, so I always think it’s best to start with a low dose and wait to see how it affects you.
