In the USA? No you cannot use paypal or any other regular 3rd party processor or merchant account. You will either not be approved or you will get shut down and at some point and your funds will be put on hold for 90-180 days. I know. been there, done that. If anyone does a chargeback during that 90-180 days, the merchant bank provider (or paypal) will give the customer the full refund from YOUR funds and let the customer keep the item as well as charge you administration and chargeback fees.
You need what is called a High Risk merchant account. Basically vape has been categorized by USA banks as "High Risk" items (same as firearms) so you have to get a high risk merchant account with has harder approval guidelines and higher rates.
Some MOTO merchant accounts like Square do allow the sale of vape but only in face to face, offline sales.
