Question says it all really
No. The minimal lethal dose recorded was 1,6 g.
" The toxic dose is about 1 g. In 104 cases
reported in literature the mean toxic (but
non lethal) dose was 1.75 g (Gross 1991)
although survival has been reported after
ingestion of 5 to 8 g (Lagerfeldt & Matell,
1982; Tynan et al., 1981). Khan & Miller
(1985) reported survival of a 28-year-old man
following ingestion of 3 g.
The minimal lethal dose reported was 1.6 g in
a 57-year-old man (Auzepy et al., 1983). The
mean lethal dose in 17 cases reported in the
literature was 5.85 g although there is wide
interindividual variation (Gross,
1991)."
