Yes, you can travel domestically, but follow carrier and venue rules.Low THC pens are legal across the UK, so there are no legal issues when traveling with it. However, keep in mind that things differ if you plan to travel outside the UK.
Also remember to keep your device and cartridges in hand luggage, observe airline battery policies, and respect liquid limits at security. Many transport services restrict vaping on board and in stations. Carry products in original packaging, and store them upright to prevent leaks. If plans include public spaces, check local vaping policies before use.
