Dust grains expelled from cool stars are injected into interstellar clouds with typical velocities of ~ 103 km s–1. The interaction of such high-speed grains with gas is discussed. Grains are preferentially stopped within clouds of number density nH ≈ 10–30 cm–3. Collisions of grains with gas atoms could lead to heating and ionization of clouds and to the production of displacement defects in grains.
