and young adults who are using e-cigarettes. we are also seeing a lot of teens with use that implies that they have very high levels of addiction. >> reporter: the cdc says no specific vaping product has been conclusively linked to all the illnesses. in a statement to cbs news, leading e-cigarette manufacturer juul says it's monitoring these reports, and we have robust safety monitoring systems in place. it noted some teenagers were vaping both nicotine and thc. a schedule 1 controlled substance that we do not sell. the cdc says in many cases patients did tell health officials they had recently used vaping products with thc, an active ingredient in marijuana, in addition to traditional e-cigarettes with nicotine. >> the major point that i would like to get across to parents is that e-cigarettes are not safe. we're seeing some very, very concerning health effects, and we really don't know exactly what the long-term data is going to show.

>> reporter: tristan's doctor says the scarring in his lungs could have a long-term effect, but he is expected to live what she calls a fairly normal life. >> these days you can find cbd in just about everything. from ointments and oils, candies and even drinks at a bar. it's been touted as a cure for everything from depression to forgivefulness, but what is cbd? where does it come from? and more importantly, is it legal? lee cowan went hunting for the answers for cbs sunday morning. >> reporter: it looks like pot, can be vaped like pot. even eaten like pot. but pot it is not. it's called cbd, short for cannibidiole that's on a real market high. >> you've never done it, start off with a small bottle to see where it goes. >> work your way up from there. >> reporter: cbd is extracted from hemp, same family as marijuana. but cbd won't have you

at least not entirely. according to the fda, it's still against the law for cbd manufacturers to make any health-related claims about their products. and companies that add cbd to food and beverages do so knowing they're operating in legally murky waters. that's because large scientific studies on cbd are way behind its new found popularity. even what dose to take is in question. >> we're having people consume this compound in large quantities, and we don't know the full health impact. >> reporter: yasmin hurd is at mount sinai hospital in new york. she said cbd is showing promise, but a healthy dose of skepticism sure won't hurt. >> it's not going to work for everyone. no drug works for everyone. >> reporter: the fda has approved one cbd drug called epidialex used to treat seizures and certain forms of childhood epilepsy. >> we're getting close. >> reporter: and hurd's own research suggests cbd may curb

addiions toeroinnd other dangerous opioids. we could be at a tipping point with the research. >> the research to date gives us a big promise on which to build. >> reporter: are you skeptical about it at first? >> absolutely, 100%. >> reporter: laura finn tez is threading the needle between the scientific and the anecdotal evidence. >> i started making products way back and we gave them to friends and family and it started working. i was like, this is -- what's happening here? it's working. >> reporter: the one-time pharmacist jumped into the cbd market feet first trusting that the research will follow. you must have a pretty strong faith in what this does for you to give up your career to do this. >> i do. i do. i have a really strong faith in it. >> reporter: you don't know exactly what the potential is, but you know there is -- >> there is great potential. >> thank you for calling green rote, this is emily. >> reporter: her company is one of the largest cbd companies in the market cornering a 10% share

of the cbd market. its sales force is made up of mostly 20 somethings who feel like they're on the cutting edge of something big. >> i'm proud, i'm blessed i'm grateful to say we're at r from quarter 1, 2018, to quarter 1, 2019. >> reporter: national chains like cvs and walgreens have announced to carry cbd products in their stores. it's already in department stores like knee man marcus. analysts say it's only a matter of time cbd is as mainstream as coca-cola. a drug, a supplement, a fad. cbd may just be all three. >> the "cbs overnight news" will be right back.
