Professional, ready made, bottle-neck smoking pipes.
(professionally made smoking pipes containing a mixture of tobacco and hemp[similar to CBD] - sedative).
For now the price is high but might come down as order numbers increase.
(right now it would take a few days/weeks for me to make a homemade one, depending on the size and locality - £50 to £5000)
Licence to be acquired (if needed) as soon as an order is placed and monies received, country depending. Non-refundable. For risk-free private and or personal usage, you take all the risk.
