The high from cannabis edibles and cannabis-infused products tends to be stronger and last longer than from smoking. As a result, overindulging on cannabis edibles can be uncomfortable and lead to what we call “Riding the Crazy Train.” Yep, we stepped aboard that locomotive more than once during our past two years of research, and let’s just say that the view out the window was blurred. We definitely don’t want you going there.
Cannabis consumables can take up to two hours to kick in fully.  Don’t make the mistake of thinking after 30 or 40 minutes that nothing is happening, and drinking or eating more. WAIT. Too many people make this mistake and have a bad experience.
Here is the gist of a white paper Amanda wrote on the subject for her teenage daughters (Jen wasn’t kidding when she said Amanda is a nerd):  If someone offers you a homemade brownie, cookie, candy — anything — and there is no label on the package indicating how strong it is, that probably means no one knows and it is likely very strong. Eat either none at all or just a TINY corner. Emphasis on tiny, or you could easily end up riding the Crazy Train for an hour or two.
If you are offered a cannabis edible that is medicinally packaged and lists a dosage, here is a guide: start with 5mg of THC, which is half the legal dose in most legal cannabis states. Just 5mg is plenty to get most people sanely buzzed. Keep in mind that 10mg is the maximum legal dose in legal states, although it’s not uncommon to find cannabis chocolate bars that offer 1,000mg of THC. Those are meant for ill patients — people really in need of cannabis medicine for pain or cancer or some other disease — and who are highly habituated. We recommend taking 5mg or less to begin. Remember, 10mg can be a lot (of fun) unless you are used to cannabis. Start low and go slow. Wait TWO HOURS for full effect. Cannabis takes much longer to kick in when ingested as it goes through the liver before entering the bloodstream.
