Much like traditional kinds of edibles with psychoactive effects, delta-8 THC may take a while before it kicks in. Some users have reported getting the feeling of a high after 30 minutes, while others say it can take anywhere between two to four hours before the effects reach their peak. It is important to note that since edibles will take longer to feel the effect than other forms like disposables, which can take seconds, it is best to wait at least an hour before taking another edible to be sure you know how the first one will affect you.
