To the Editor.—
In the article entitled "Cocaine and Marijuana Use by Medical Students Before and During Medical School" that appeared in the April issue of the ARCHIVES,1 errors occurred in Table 3. Although the manuscript was read and reread countless times and the galley proofs were also read, I am embarrassed to say that Table 3 has inaccurate numbers in each column and an incorrect horizontal heading. Table 3 with the corrected horizontal heading and percentages should have read as shown in the table reprinted with this letter.I accept responsibility for the error. The meaning of Table 3 is unchanged.
