The Jack the Ripper Glass Pipe from SI Pipes is a classic example of a one-hitter. It is the ideal size to use anywhere without attracting so much attention. It is also the perfect size to use cannabis from (whether recreational or medical marijuana) because it can fit inside your pocket. The Jack the Ripper Double Filtered refillable handheld glass pipe is easy to use but could be a challenge to clean.
This pipe can also be used to smoke medical cannabis. This is a good way to take cannabis but there are some complaints. First of all, it is a pain to clean because of the small parts. You need to use cleaning chemicals to remove all residue but you also need to scrub it well to remove the cleaning chemicals as well as dirt and residue that have accumulated inside the pipe. Other than some flaws, this remains a good one-hitter pipe to use for enjoying cannabis.
