You're on the wrong side of town bro! I don't know if there's any Laws or regulations against it... I remember big crackdowns years ago on bongs and such but haven't heard anything regarding vapes.
Anyway, village bazaar on sixth and washington has a nice selection of vapes. Last time there I saw pinnacles, paxs, newer model mflbs... Even picked up a VBWT without logo a few days after I saw them on here for $70.
NY gifts has a great glass selection and oil pens.
The SmokeKing on Christopher and seventh has real nice glass too and lots of oil accessories.
There's also a few on fourth street btwn 6-7 but I find those places to be a bit naive on what's good in vapes. Mostly the thinking is high priced item = better.
All of these places can be haggled w a bit. I've gotten stuff for half what they offered at first just by offering cash.
Also, my local newspaper joint/smoke shops in the Boros even carry lots of glass accessories and even had the pinnacle and a NO2. Overpriced to boot... But they had em.
Btw... Noticed lots of these shops have a huge selection of oil accessories. Has oil become really big in NYC?
This would be so much more convenient for us vapers but are there specific laws against this kind of retail store? I know that stores by st. marks sell many low level bongs with ROOR stickers but there aren't any actual stores that support the vape market with good products.
