(Bloomberg) -- German lawmakers will approve delayed legislation decriminalizing personal use of cannabis this week, paving the way for it to take effect on April 1, according to Health Minister Karl Lauterbach.

The law, set to pass the lower house of parliament by Friday at the latest, would allow adults to posses as much as 25 grams of cannabis, grow a maximum of three plants for private consumption and cultivate the drug as part of nonprofit cannabis clubs limited to 500 members.
