Smoking a pack of cigarettes a day is equivalent to an exposure level of
1,000 micrograms of toluene.

This is enough according to the FDA to cause birth defects.

Condoms contain hundreds of times more toluene then this.

What recommendations has the federal government made to protect human
health?

The federal government has developed regulatory standards and guidelines
to protect you from the possible health effects of toluene in the
environment. The Occupational Safety and Health Administration (OSHA) has
set a limit of 100 ppm of toluene for air in the workplace, averaged for
an 8-hour exposure per day over a 40-hour work week. The American
Conference of Governmental Industrial Hygienists (ACGIH) and the National
Institute for Occupational Safety and Health (NIOSH) have recommended
that
toluene in workplace air not exceed 100 ppm (as an average level over 8
hours). 

Condom manufacturers add toluene to per vulc. latex to aid mixing during
ball milling. The quantities used are substantial (like adding paint
thinner to your paint) and VASTLY in excess of the 100 parts per million
(one part per 10,000 of latex) considered the maximum safe level.

Condoms clearly cause birth defects. If not then what we have been told
about cigarettes causing birth defects is quite impossible.
