As a nutritionist, I'm not a fan of smoking anything — tobacco, cannabis, or herbs. Inhaling burned plant material delivers tar, carbon monoxide, fine particulates, and other combustion byproducts straight into your lungs, and that carries real risk no matter which plant you're burning.
That said, herbal smoking has a long history across many cultures, and people are genuinely curious about herbs like mullein, damiana, and lavender. So let's take an honest look: what people traditionally use smoked herbs for, the real risks (which are usually understated), the most popular herbs and what they do — and safer ways to get the same benefits without putting smoke in your lungs.

What Are Herbal Smoking Blends?
Herbal smoking blends — sometimes sold as herbal cigarettes or "herbal smokes" — are mixes of dried, non-tobacco plants like mullein, damiana, raspberry leaf, mugwort, lavender, and rose petals. They're nicotine-free, which is why many people try them to wean off tobacco, as a ritual, or as a base for other smoking products.
Here's the key thing to understand: nicotine-free doesn't mean harmless. Research comparing herbal cigarettes to tobacco has found they still produce tar, carbon monoxide, and carcinogens at comparable levels.(2)(6) The danger in smoke comes mostly from combustion itself, not just from what's being burned.
Potential Benefits of Smoking Herbs (Traditional & Preliminary Evidence)
Certain herbs have been smoked for ceremonial, medicinal, or recreational purposes for centuries.(1) Traditional use and limited modern research suggest possible effects in areas like relaxation, respiratory comfort, and mood. But almost all of these benefits can be reached more safely another way — tea, tincture, steam, or aromatherapy.
As I tell clients: everything in health comes with trade-offs. With smoking herbs, there may be some surface-level benefits, but the trade-off — smoke in your lungs — is a steep one. Smoking is rarely, if ever, the best route.
Commonly reported traditional benefits include:
Respiratory comfort — Mullein is traditionally used as an expectorant to help loosen mucus and soothe airways.
Relaxation and mood support — Damiana, lavender, chamomile, and passionflower are often smoked for their calming, mildly sedating effects.
Dream enhancement — Mugwort is known in herbal traditions as a "dream herb" for vivid or lucid dreaming.
Uplift and libido — Damiana and rose are historically associated with mood elevation and gentle libido support.
Sinus clearing — Cloves have traditionally been added to blends to open the sinuses.
These effects come mostly from traditional herbalism, anecdotal reports, and small or preclinical studies on the herbs' compounds — not from solid human trials on smoking them. They map to specific herbal actions like expectorant and nervine, which work regardless of how you take the herb.
Real Health Risks of Smoking Herbs
No matter how "natural" the herb, smoke is smoke. Burning plant material produces tar, carbon monoxide, polycyclic aromatic hydrocarbons (PAHs), and fine particulates — the same classes of harmful byproducts found in tobacco smoke.(4)(6)
Lung irritation and inflammation — Smoke inflames the airways, increases mucus, and can cause coughing, wheezing, or shortness of breath.
Chronic respiratory problems — Regular smoking can contribute to bronchitis-like symptoms, reduced lung function, and worsening asthma or COPD.
Cardiovascular strain — Carbon monoxide reduces oxygen delivery to your tissues, and particulates and inflammation are linked to heart disease.
Cancer risk — Combustion creates known carcinogens, and lab studies of herbal cigarettes show toxicity profiles similar to tobacco.(2)
Herb-specific effects — Some herbs can cause drowsiness (chamomile, passionflower), stronger effects at higher amounts (mugwort, blue lotus), allergic reactions, or sinus irritation.
Pregnancy: Don't smoke herbs while pregnant or breastfeeding. Smoke exposure carries risks for the baby regardless of the plant, and several traditional smoking herbs (like mugwort) are specifically avoided in pregnancy.
Popular Herbs People Smoke
Here's a short profile of the most commonly smoked herbs — and the safer way to get each one's benefits.
Mullein
Mullein is the most common base in herbal smoking blends. It's prized as a respiratory soother with expectorant action that may help loosen and clear mucus, and its smoke is mild compared to tobacco. But mullein tea or steam inhalation delivers the same mucus-clearing support without the smoke. We cover it in depth in our guide to mullein's benefits, traditional uses, and safety.
Damiana
Damiana has a traditional reputation as a mood enhancer and aphrodisiac, and smoked, it produces a gentle, relaxing lift. Damiana tea or tincture gets you the same mood and libido support far more safely.
Can You Smoke Lavender?
You can — dried lavender is a common ingredient in herbal smoking blends, and people smoke it for its floral taste and calming effect. But you shouldn't expect it to be safe just because it's lavender: burning it creates the same combustion byproducts as any other plant. Lavender's calming benefits are well documented through aromatherapy, so diffusing lavender essential oil or drinking lavender tea gets you the relaxation without the smoke.
Chamomile
One of the gentlest calming herbs, chamomile is sometimes smoked to ease anxiety and support sleep. Chamomile tea remains the gold standard.
Mugwort
Mugwort is legendary as a "dream herb" — smoked before bed to promote vivid or lucid dreams. Mugwort tea or a pillow sachet offers the same traditional use without the lungs taking a hit. Avoid it entirely during pregnancy.
Passionflower
A classic for calming a busy mind and supporting sleep. Passionflower tea or tincture is at least as effective and completely smoke-free.
Rose
Rose petals are added to blends for a light, uplifting quality and flavor. Rose tea, rose water, or rose-infused honey delivers the same gentle support without inhalation.
Cloves
Cloves add a spicy, sinus-clearing quality to some blends, thanks to eugenol. Clove tea or steam inhalation provides the same clearing effect without burning.
Blue Lotus
Blue lotus has a long ceremonial history for mild calming and subtly mood-altering effects. It's more potent than most herbs on this list, so it deserves extra caution. Tea or a low-dose tincture is the safer way to explore it.
Safer Alternatives to Smoking Herbs
If you're drawn to these herbs for relaxation, respiratory comfort, mood, or dreams, there are much lower-risk ways to get there:
Tea or infusions — Most of these herbs release their active compounds well in hot water.
Tinctures — Concentrated liquid extracts under the tongue or in water. Read more about how tinctures work.
Aromatherapy or steam inhalation — Diffused essential oils or herbal steam for calming and respiratory support.
Low-temperature vaporizing — If you want to inhale, a quality dry-herb vaporizer at low heat releases aromatic compounds without combustion. It's lower-risk than smoking, though not risk-free.
Topical or oral use — Salves, capsules, or herbal honeys.
For respiratory support specifically, our Lung Clear & Support Tonic delivers concentrated mullein, osha root, and other lung-supportive herbs as a liquid extract — no combustion involved.† For calm and relaxation, our Complete Stress & Cortisol Balance Protocol uses calming herbs in liquid form.† See also our guide to expectorant herbs for lung health.
The Bottom Line
Smoking herbs can feel ceremonial or nostalgic, and the plants themselves carry real traditional wisdom. But your lungs are delicate, and any smoke adds irritation, inflammation, and long-term risk. Herbal smoking blends aren't a safe alternative to tobacco — they're just a different kind of smoke. My advice is always to take the path of least harm, and that almost always means skipping the smoke and getting the same herbs through tea, tinctures, or aromatherapy.
