There is a difference not only in onset, but also duration when comparing smoked versus ingested THC. THC9 is converted to THC11 when processed by the liver. One of the notable differences between 9 and 11 is that the effects are considerably longer lasting. It is lacking the "peak" that people who toke enjoy most, though. The effect takes longer to begin, but it stays active in your system a lot longer. Instead of smoking repeatedly through the evening, you can ingest once and you're pretty good for the next 4 or 5 hours, or more depending on how much you take. That's pretty efficient. Anecdotally, if I smoke before bed, I wake up completely sober. But if I ingest (via capsules, but of course tea, or brownies, etc. would all work) before bed, I'm still high when I wake up. If you use cannabis for sleep issues, it seems ingesting it is about as efficient as you could hope it to be. My recipe for getting baked and staying baked without having to "top it up": Take a couple of THC capsules, and then smoke up. That way you can spend the hour or so enjoying the smoked herb peak before the ingested THC starts taking effect. While the smoked cannabis is waning, the pills are starting to kick in. It's nearly seamless.
