Dealing with travel anxiety? Bring your aromatherapy on the go with a MONQ personal inhaler, which combines a blend of organic essential oils and plant extracts to bring total relaxation to the mind and spirit. Simply inhale the gentle vapor from the device into your mouth, and exhale it through your nose to get the full zen effect. Though these can't be used on planes, many airports do allow them in seating areas and public spaces.
Note: MONQ's devices are nothing like e-cigarettes aside from the basic vapor technology they use. These are completely natural, free of nicotine, and use no artificial chemicals. Using them is basically like breathing in the vapor from a regular essential oil diffuser.
