Sera Labs CBD Oil is a difficult substance because it is not absorbed very well orally, explained Welty. Less than 20 percent of the substance is absorbed orally, and if it is not produced properly, there may not be much of the substance in the systemic circulation.
And even worse, about 1 of every 5 Sera Labs CBD Oil products contained the substance of the drug marijuana, THC, found by Bonn-Miller and his collaborators. Nearly 43 percent of the products contained too little CBD, while about 26 percent contained too much, Bonn-Miller said.
This is a problem because THC can increase anxiety – it can actually make seizures worse – it’s the kind of thing you have to be careful about, Bonn-Miller cautioned. If it were a consumer who buys it for me or my son, I’d like to be evaluated to know what it really contains, because I would not trust what the label says, Bonn-Miller concluded.
