Smoking... FLOWERS??

so my friend had to quit weed, so for anxiety he smokes flowers... like the actual plants. he goes to this herb shop and gets a combo of flowers like Lavender and hops and blue vervain etc... its supposed to help for anxiety or whatever combo you create... my question is, has anyone tried flowers? or a more natural route??

i probably wouldnt smoke them but would try essential oils in a roller bottle applied to the temples/wrists. Smoking anything risks damage to your lungs, theres so many different combinations you can use with the oils for anxiety.
