At what point does tobacco affect bones?

From the first years of smoking, but the effect is mainly measurable after 10-15 years. Young smokers' bone density is already lower than their non-smoker peers'.

Does tobacco really lower the effectiveness of menopausal hormone therapy?

Yes, partly. Several studies show oral oestrogens are less bioavailable in smokers. Patch (transdermal) oestrogens are less affected.

Does vaping have the same effect on bones?

Pure nicotine has a slight anti-osteoblast effect. But without combustion or CO, the bone effect is probably much less than the cigarette. Studies ongoing.

If I quit at 60, is it too late for my bones?

No. At any age, quitting stabilises bone loss. Fracture-risk benefits are measurable even in late quitters.

Do snus and chewing tobacco also affect bones?

Data are weaker, but nicotine is there. Likely bone effects, probably less than with combustion.

Smoking and osteoporosis: how cigarettes weaken your bones, especially in women

Tobacco raises osteoporotic fracture risk by 30-40 %. Early menopause, lower calcium, vascular damage: why bones suffer.

May 15, 2026 Aria

Osteoporosis is the silent disease that makes bones fragile and prone to fractures — often unnoticed until the first break. Less known is that tobacco is a major risk factor for osteoporosis, particularly in women.

Why bones take the hit

+ 71 % hip-fracture risk at 80 in persistent smokers, compared with non-smokers.

Vestergaard et al., Bone, 2003; later meta-analyses

Why women are particularly affected

Osteoporosis is already more common in women, because of menopause (oestrogen drop, which protects bone). Tobacco worsens this in several ways:

A 55-year-old woman smoker has the bone density of a 60-year-old non-smoker. Tobacco silently ages bone, and the first sign is often a fracture you did not see coming.

Myth vs reality

Recovery after quitting

A few months bone loss slows clearly.
1-2 years bone density stabilises.
5+ years density starts climbing back (partial catch-up, especially in younger people).
10 years after quitting hip-fracture risk approaches that of a non-smoker.
