You would have to drink a lot of oil in order to have a CBD overdose.
You may already know that any chemical substance could kill you in a high enough dose. This dose is known as the LD50. A recent article from Current Drug Safety established an LD50 for CBD of 200mg per kg of body weight. This is almost identical to the LD50 for caffeine.
That means the average person would have to drink 4-5 entire bottles back to back of our strongest CBD oil (4000mg) in order to overdose.
We highly recommend you don’t do this. Instead, we recommend you take a half to a full dropper full twice a day and enjoy your life.
