Your friend is mistaken:
Effects of Exposure: Titanium is generally considered to be physiologically inert. There are no reported cases in the literature where titanium as such has caused human intoxication. The dusts of titanium or most titanium compounds such as titanium oxide may be placed in the nuisance category.
Acute Effects: -Titanium 2-
Inhalation: Prolonged inhalation may cause mild irritation to the lungs and respiratory tract. I
ngestion: Relatively non-toxic, poorly absorbed from the alimentary tract.
Skin: May cause abrasive irritation.
Eyes: Dust or powder may cause irritation.
Chronic Effects: None known
Medical Conditions Generally Aggravated by Exposure: Any preexisting respiratory problems. Target Organs: Mucous membranes Routes of Entry: Inhalation, ingestion, skin, eyes.
Carcinogenicity: NTP: No IARC: No OSHA: No EPA: No
Other: Questionable carcinogen with experimental tumorigenic data. Experimental reproductive effects.
